You'll be fine. In my old PB 12", I replaced the stock 5400 RPM with a 7200 RPM. And no real heat issues. The 5400 was warm to begin with, and the 7200 didn't make much of a difference... In hind sight, the faster RPM drive didn't make much of a performance impact.

i put a 7200RPM drive in my pc laptop and it was a performance improvement there but then it had a 4200rpm in their originally, but the difference between the 5400rpm and the 7200rpm drives in notebooks probably doesn't justify the extra cost of 7200rpm
